heal.abstract	In the present work, the main decay phenomena of the various lithotypes of the ancient Sanctuary of Demeter (1600BC) in Eleusis-Greece are studied in respect of the environmental factors under monitoring, concerning an area characterised by a heavy industrial pollution in an intense marine environment. Stone surface alterations are studied by examining the various neoformations. Specific investigation has been performed on the depositions of the total suspended particles, mainly characterising the polluted atmosphere in the Thriassian plain, as possible weathering causes. OM, SEM, EDX and XRD analysis are employed consequently. Decay phenomena like crust formations (gypsum, loose depositions of soot and suspended particles, at the more or less sheltered areas), various cementitious encrustations on the marble surfaces, especially the horizontal ones, or Fe-rich yellow patinas on the washed out surfaces are evidenced. These weathering phenomena might be attributed to pollutants, suspended particles and their wet and dry depositions, which are measured according to the analysis performed. Moreover, the newly evidenced decay pattern of 'cementitious encrustations' (rich in Ca-Si-Al complexes, which characterises the flying ash coming from the nearby cement industry) and its hydration products, may be attributed to a 'cement coating' that exerts pressures to the marble surface and triggers pitting phenomena. Hence, preservation policy planning should recall for an appropriate management of the emission sources.	en
